چکیده
Compact terahertz (THz) devices, especially for nonlinear THz components, have received more and attention due to their potential applications in nonlinearity-based sensing, communications, computing devices. However, effective means enhance, control, confine the harmonics of waves remain a great challenge micro-scale In this work, we established technique harmonic generation based on phonon polariton-enhanced giant nonlinearity 2D-topologically protected valley photonic microcavity. Effective has been observed both noncentrosymmetric centrosymmetric materials. These results can provide valuable reference control high-harmonics, thus developing new devices regime.

Generation of second-harmonic conical waves via nonlinear bragg diffraction.
We report on the observation of second-harmonic conical waves generated in a novel geometry of the transverse excitation of an annular periodically poled nonlinear photonic structure by a fundamental Gaussian beam. We show that the conical beams are formed as a result of the higher-order nonlinear Bragg diffraction involving two parametric processes in which an ordinary fundamental wave is conv...
متن کاملA Quantum Dot Microcavity Terahertz Laser
We discuss a THz laser device based on a semiconductor quantum dot (QD) gain medium, where the lasing occurs through discrete conduction states. An ensemble of QDs is selectively placed in a high quality cavity, called a microdisk, which is resonant with a terahertz intersublevel QD transition. We simulate the rate equations goveming iasing and discuss a variety of processes affecting lasing in...
